Comment: Giant untreated white sapphire with tingles of green, blue and yellow. Always better than image. This is a beautiful rock, wild perhaps but immediately charming with a liquid crystal and that natural silky hue that is only found in unheated sapphire. We only wish it would be easier to photograph. One of the biggest white sapphires available. Well cut, pleasing classic shape and dimensions. Collector item. Great gem for a kingly gent's ring. Unheated sapphire over ten carat!
